We need to run sites in SharePoint 2010 mode as we migrate each collection and train each department. Everything works just like in real 2010 except I can't install Office Web Apps 2010, installation fails.
Does anyone know a way to maintain the same Office Web App functionality on sites running in 2010 mode on 2013?
FYI: We have office web apps 2013 installed and functional for sites in 2013 mode.
